There you go again Ms. Stipe. I challenge you to find specific language in the Constitution of the United States that says "separation of church and state."
If you are referencing the First Amendment, then let us see what it says: "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for redress of grievances."
The part you don't want to acknowledge gives us all the right to express our choice in religion. If what you say is true, then why does our official "National Anthem" have "in God is our trust" in the last chorus? Why does the Declaration of Independence state that "all men are created equal, that they are endowed by their Creator with certain unalienable rights."
